AFV: Programmable Full-Featured AC Source

Intepro Systems in conjunction with Preen offers a programmable AC source with power ratings up to 2MVA

Achieving this high power paired with its advanced features make the AFV an ideal solution for R&D and compliance testing. The AFV offers a comprehensive protection scheme including: OVP, UVP, OCP, OPP, OTP and SCP. The AFV series employs an impressive touchscreen display that allows for complete local operation. Users can also achieve control via the included standard RS-485 interface or optional RS-232/GPIB.

Featured Benefits
  • Output Power 10kVA -2MVA
  • Efficiency is 85% to 90%
  • Three Phase Independent Control
  • STEP and GRADUAL Features

AFV series programmable AC power source
Applications
  • Home Appliance
  • Laboratory/Certification Bureau
  • Industrial Power Supply
  • Motor & Compressor
  • IT / SMT Production Line
  • Renewable Energy
  • Electric Vehicles
  • Transportation
AFV Series
  • CE & RoHS certificated.
  • Modularized inverter which is compact, smaller, high power density and easy to maintain.
  • 7-inch touch screen which can display the phase voltage, current, frequency, active/apparent power, power factor and test information.
  • Ability to simulate abnormal power status: STEP and GRADUAL change modes allow users to set sequences of start/end voltage, frequency and running time with ease.
  • Comprehensive protections which include output undervoltage / overvoltage, overcurrent, overload, input undervoltage / overvoltage, overheat and other more than twenty fault conditions.
  • Three-phase voltage independently adjustable function: each phase voltage can be adjusted independently; therefore AFV can power more than one single-phase loads.
  • Phase angle adjustment function: can adjust the phase angle between each phase (for three phase system).

Preen’s AFV series is a programmable AC power source that can be remotely controlled and integrated with other systems for automatic testing. AFV series provides precise output voltage and frequency which could reach various types of industrial requirements. For the industrial users, such as home appliances, electrical and electronic, medical equipment and lighting, they are able to quickly and accurately simulate standard or abnormal power status via programmable function.

AFV builds-in standard programmable features, such as STEP and GRADUAL features, which are ideal for laboratories, certification and R&D institution’s compliance test.

The user friendly touch screen supports user to operate AFV series intuitive and easily, and the user can remote control the unit via the standard RS-485 or RS232 (Optional for Ethernet, GPIB) interface. The AC source is coupled with output voltage range of 0~300V and output frequency of standard 45~65Hz or optional 45~500Hz. Moreover, the AFV series provides complete product protection, such as OVP, UVP, OCP, OPP, OTP and short circuit protection.

User-friendly Touch Screen and Remote Control

Image

AFV with 7-inch touch screen of intuitive operation, easy to operate, quick setting, easy to use. Through the remote control interface (RS-485 / RS-232 / GPIB / Ethernet), users can set the desired output parameters and monitor the output value.

STEP Mode

Image

AFV series has the STEP change mode which provides up to 24 sequences and up to 255 cycles. The output voltage, frequency, and running time in each sequence can be set on the touch screen. These functions are widely used in the performance test of electric motor or home appliance load.

GRADUAL Mode

Image

AFV series has the GRADUAL change mode which provides up to 12 sequences and up to 255 cycles. Through this feature, users are allowed to set the product output, such as start/end output voltage, start/end output frequency and dwell time of performing the GRADUAL feature in each of the adjustable sets, and then the product output will change according to the setting slew rate.

Soft Start Features (Opt.)

Image

Soft-start function can effectively reduce the starting current of motor load or inductive load. The users have more flexibility on selection of power capacity and more efficiency on space usage. They can purchase more cost-effective products.

Three Phase Independent Control (Opt.)

Users are allowed to control three-phase output voltage independently. The product can be used as one unit of three-phase power supply or as three units of single-phase power supply.

Wide Variety of Applications

Image

With its high reliability, capability of complex power line simulation and high output power, the AFV series has been widely applied for applications on home appliance, electric vehicle charger, motor, electronics and medical equipment. It is a AC power source suitable from R&D verification to mass production testing.
